(E,E)-二(2-羟基苄亚基)丙酮(2-HBA)

(E,E)-Bis(2-hydroxybenzylidene)acetone (2-HBA) is a synthetic analogue of curcumin that displays strong NAD(P)H:quinone reductase (NQO1) inducer potency in Hepa 1c1c7 cells. 2-HBA, a double Michael reaction acceptor, can directly modify cysteine sulfhydryl groups in Keap1 and consequently suppress Nrf2 ubiquitination which in turn enhances the expression of antioxidative and cytoprotective enzymes. 2-HBA has also been shown to cause G2/M cell cycle arrest and p53-independent, caspase 3-mediated apoptosis.
